This chart, which I published a while back, illustrates how well horizontal lines work. Thing 1 (in the ellipse) was the first major decline on increased volume in February of 2018. This was followed by a recovery and marginal new high between mid September and October firs. The decline that followed, creating thing 2 (in the ellipse) was almost a mirror image of thing 1. The horizontal line of support at 2528.26 labeled oops, failed opening the door to 2415.75 and then 2322.75. Please take note that the decline this past week was on very high volume which looks much like a flush out.
